网上的教程一大堆，大同小异
编译好以后sudo insmod secbulk.ko
dmesg
出现以下信息
[ 872.099542] secbulk: module verification failed: signature and/or required key missing - tainting kernel
[ 872.100810] secbulk:secbulk loaded
[ 872.100888] usbcore: registered new interface driver secbulk
哪位能帮我看看是为什么
另外，我编译了官方的uboot，制作了sd启动卡，启动tiny4412后，串口打印数据正常，但是tiny4412的屏幕上什么都没有，这是正常的吗？
